The main factor that determines the length of time for old feathers to shed and new feathers to grow is the particular breed of chicken.
Your most productive layers will molt the fastest.
They go through hard molts, whereby clutches of feathers seemingly drop overnight. It’s sometimes hard to believe that big old pile of feathers came from only one chicken!
Hard molters can resemble porcupines (hilariously so!) and while their appearance is a little unsightly at this stage, they usually have fluffy new coats within weeks of their first feather drop.
Hard molters generally resume egg production after finishing their molts, which explains why certain chickens continue laying through the dark days of winter.
